New Aalberg Audio KOR KO-1 Chorus/Flanger Guitar Effects Pedal with Wireless Control

The KOR KO-1 Chorus/Flanger Pedal from Aalberg Audio is a high-quality stereo in/out combined chorus and flanger stompbox that can be controlled wirelessly with the optional AERO AE-1 controller (NOT INCLUDED). The pedal offers different mono and stereo configurations including a dry/wet split and stereo panning from left to right, giving a more spacious feel to the flanger or chorus effect.

The KOR Chorus/Flanger can also be controlled by a free iOS/Android remote app that provides easy editing and allows the saving of presets for later recall. All the electronics are contained in a rugged, custom-made aluminum housing, while the onboard purple LED bars at the top provide actual parameter settings, easily seen from a distance or in low light. The KOR is powered by an optional 9V adapter (NOT INCLUDED).

Input/Output Setups
  • Mono In/Mono Out: Connect your instrument to Mono In and the amplifier to Mono Out
  • Mono to Stereo Spread: Connect your instrument to Mono In, then connect one amplifier to Mono Out, and another amplifier to Stereo Out. The stereo spread effect is a combination of phase inversion and a continuous panning of the signal from side to side, resulting in a wide stereo effect
  • Dry/Wet Split: Connecting your instrument to Stereo In will split the dry wet signal as follows
    • Mono Out: 100% wet signal
    • Stereo Out: 100% dry signal
  • Stereo to Stereo Spread: By plugging into both the mono and stereo inputs, and both mono and stereo outputs, you will obtain the same stereo spread effect achieved with the Mono to Stereo Spread connections. This is useful if you want to maintain the stereo image from the output of another pedal in your signal chain
